Title: Improvements in or relating to the manufacture of moulding compositions from phenol-aldehyde synthetic resins
IPC: C08L61/10
Filed: 1936-06-16
Abstract: A moulding-composition is produced from a hardenable phenol-aldehyde resin in the resitol stage by subjecting the resin in a finely divided form and in the presence of a quantity of water or other non-solvent liquid insufficient to produce an emulsion to an intensive mixing treatment, e.g. on cold or heated calender rolls. The product is solid and dry-looking and may be moulded without fillers.  Xylene, toluene, or an aqueous suspension of toluene may be used instead of water.  The non-solvent liquid may be added before, during, and after mixing, and, during mixing, differently coloured resin, other natural or synthetic resins, plasticizers, oxidized castor oil, stearic acid, spermaceti, or dyes may be added, e.g. dissolved or suspended in the non-solvent.  The resitol may be prepared from phenol and formaldehyde solution by heating in the presence of calcium carbonate, boiling down to separate the resin, and heating to produce a water-containing resitol which may be treated as such or after drying; or a novolak resin made from phenol and formaldehyde solution in the presence of hydrochloric acid may be heated with hexamethylene tetramine.  Phenol-aldehyde resins containing further components such as fatty oils may be treated.

Abstract: A method of eliminating the internal tack from an elastomeric flexible cellular structure prepared by reaction of an active-hydrogencontaining polymeric material, a polyisocyanate and water comprises treating the cellular material with silicone oil. The term "active-hydrogen-containing polymeric materials" denotes polyesters, polyesteramides and polyalkylene ether glycols. Preferred are polyester and polyesteramides having an average molecular weight of about 750 to 2,250, an acid number not greater than 5 and a hydroxyl number from 50 to 150.  The silicone oil can be applied to the cellular material by wiping the surface with a rag impregnated with silicone oil, by using silicone oil impregnated squeeze rolls, by covering the structures with an oilimpregnated rag and passing between squeeze rolls, by brushing or spraying the silicone oil on to the surface of the structure or by injecting the oil into the structure.  In examples, cured foamed products (obtained by treating a prepolymer from an ethylene glycol/diethylene glycol/butylene glycol/adipic acid polyester and 2,4-tolylene diisocyanate with a mixture of 2,4-tolylene diisocyanate, water, castor oil and N-methylmorpholine (and, in one example, a butyraldehyde/butylamine condensate)), are treated with drops of silicone oil and compressed or kneaded until the oil penetrates.
